This patch adds code to initialize the A9 dual CPU complex in the Tegra2 SoC. The code is run on the AVP first to set up the A9 and Coresight clocks, then the AVP is halted, the A9 CPU is brought out of reset, and the code executes again on the CPU, but down a slightly different path. Normal POST then proceeds using the A9 CPU.
